I thought it was banned? Where's you get your hands on TSP? I was looking for some a couple years ago when I found out our old apartment had lead paint issues and found that no one carries it anymore. In any case, I was pregnant when I needed it. I couldn't find any, but if I had, I would have used it because I bought the proper mask.

That's so strange. I don't know why people told me it was banned (I was told this by someone at Menard's and Target).

To the OP, if you're going to use it, use heavy duty gloves and a mask specifically for that purpose. Just a random mask used for dust and such won't be enough, even if you weren't pregnant. TSP is some nasty stuff!
